Filed Nov. 2,v 1946 Patented July 18, 1950 ffUNlTED `STATI-:s PATENT OFFICE' 2,515,923 ICE sHAviNo MACHINE Ernest C. Hansen, `New Orleans, La. Application November 2, 1946, serial 1510.701364 The present invention relates to new and useful improvements in ice shaving machines and more particularly to a power operated machine of this character including a rotary cutter for shaving a block of ice into substantially fine particles.

An important object of the invention is to provide a machine of this character including a manually operated follower for feeding the block of ice in a step by step movement toward the cutter.

' An additional object of the invention is to provide a manually operated pressure plate for holding the block of ice against movement while being shaved and by means of which pressure is main- 3 Claims. (Cl. 241-92) tained on the block of ice while being fedy toward i the cutter.

A still further object is to provide a machine of this character of simple and practical construcVV tion, which is eiiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming' part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a longitudinal sectional viewof the ice chamber;

Figure 2 is a front elevational view of the maf` chine;

Figure 3 is a rear elevational View thereof;

. Figure 4 is an enlarged front elevational View of the rotary cutter;

Figure 5 is a side elevational view thereof;

p Figure 6 is a fragmentary sectional view taken on the line 6-6 of Figure 4;

Figure '7 is a top plan view of the wear plate for theice chamber;

Figure 8 is a top plan view of the pressure plate for the block of ice; and

Figure 9 is a top plan view of the follower.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a stand generally which includes a platform 6 supported on legs 1.

Front and rear standards 8 and 9 rise from the platform, the front standards having a cylindrical casing I0 supported in horizontal position thereon and with its rear end rigidly connected to the rear standards 9 by bracket structure I I on which is supported a base I2 for an electric motor I3.

The casing Ill is open at its front end and conits rear end provided with a pulley I8.

stitutes an ice chamber It therein, the rear of the chamber being closed by `an end plate l5 with which a bearing I6 is in,-A

ternally formed and supported on the rear standards 9. l

A shaft I'I is journaled in the bearings I6 with i puliley I8 is driven by a belt I9 from a pulley 20 connected to the motor I 3.

The front or inner end of the end plate I5 is' formed with an annular chamber 2l in which a cutter head 22 is operatively mounted and secured to the front end of the shaft I1.

The cutter head 22 includes a disk 23 at its 'Ifront end having a plurality of radial slots 24 between a pair of the blades 25 as shown in liig-r ure 4 of the drawings.

'A discharge spout 29 extends downwardly from the botto-m of the chamberZl and through which shaved ice is discharged under the influence of the vanes 28 which function as impellers, the

shaved ice being discharged into a receptacle 30 supported on the platform 6. Y

A `wear plate 3l is secured in the bottom of the ice chamber I 3, the upper surface of the wear plate being formed with longitudinally extending -wear plate inwardly ofthe ice chamber for the movement of the innerend of the block of ice Y into engagement with the cutter 22.

A follower 34 is secured at the inner end of a toothed bar 35 and engages the rear end of the block .of ice to move the block inwardly of the ice chamber.

A lever 36 is pivoted at its lower end by means of a conventional hinge structure 3'! to a bracket 38 secured to the lower portion of the lining I4 of the ice chamber, the lever having an opening 39 in which the toothed bar 35 is slidably received and a roller 40 is journaled in the opening for engaging the teeth 4| of the bar 35 to move the bar and the follower 34 inwardly in a step by step movement.

A pressure plate lI2 is pivotally mounted at one end by means of a conventional hinge structure 43 in the top of the ice chamber Ill to the lining I4 and has its front end formed with teeth 42a having a wooden lining Also projecting from theVA to bite into the upper surface of the block oaf ice 33.

A rod 44 is pivoted :at its lower end to the plate 42 and is slidably mounted through the top of the ice chamber I in a guide 45. To the top of the rod 44 is secured a transversely extending lever 46 with a coil spring 41 mounted on the rod 4between the lever and the top of the ice` chamber to exert its influence on the pressure plate 42 to raise the'latter. One end of' the lever 46 is pivoted as at i9 to the upper end of -a support 50 rising from one side of the ice chamber and to the other end of the lever is secured a chain 5I which extends downwardly to a foot,pedal52 which is pivotally connected to a floor 53 as shown at 54. Downward pressureibythefoot of a person exerted on the foot pedal 52will vpull the lever 46 downwardly to exert pressure on the pressure plate 42 and to hold the blockof -ice 33 rmly against the cutter 22 and at the same time the block .of ice is fed inwardly against the cutter by the follower 34 and lever 36.

.The cutter 22 is rapidly rotated by the motor I3 whereby to shave the block of ice into nne particles which are discharged through the spout 29:.intothe receptacle 30.

I.The receptacle 30 is removably supported on the-.platform 6, and if desired la funnel-shaped mold 55 may be held under the spout vZllafter the -`receptacle 30 has been removed to nll the mold ywith the powdered orshaved ice. The narrow end .of the mold 55 is provided with an ejecting plunger 5S of `conventional construction for ejecting the shaved ice packed inthe funnel. Thef-unnelhis supported in aholdera'l secured tolone of the standards 9, when not in use.

.In View of the foregoing description taken in conjunction with the accompany-ing drawings it isbelieved that -a vclear understanding of .the device will .be @quite apparent to those skilledfin this. art. ,A more detailedwdescriptionis accordingly deemed unnecessary.

It is to be understood, however, that even though there ishereinshown anddescribed-a preferred embodiment of the invention the same is Asusceptible to certain changes fullycomprehended ,by the spirit of ,the invention as herein described and theiscope of the Aappended 7claims.
